WARNING: Sometimes when you delete these doors with SHIFT+Click Object-->delete,
two bloody Abstract.RabbitHoleDoorJig will remain in the lot.

A Jig is an invisible object used to prevent routing/traffic in situations/places where animations are involved
in order to avoid clipping between Sims and/or objects. "Stray" Jigs can cause routing problems.

Deleting the doors with nuke (from AwesomeMod) or from Buy/Build Mode seems safe, but better check anyway.
Keep in mind that each RabbitHoleDoor, as well as regular RabbitHole, normally have 2 of these jigs and it's not
a good idea to delete them (this can be complicated if you have stray ones because there's no way to distinguish them).
You can check if there are leftovers and delete them with NRaas Master Controller:

- Click on the lot, select NRaas and then "NRaas Master Controller" (the one with the ImmediateInteraction symbol)
- Select "Object Stat" (I guess so, my game is localized) and as filter put "Local" and "Non Inventory"
- Select the grouped RabbitHoleDoorJigs (and only those) and delete them clicking on the "tick" icon.

UPDATES

18th Apr 2015 : Added 6 additional rabbit holes and support for the rug version. See this and my following comment.
11th Mar 2015 : BugFix (door#4 was equivalent to door#1).

MOD DESCRIPTION

Developed and tested with game version 1.67.

This is a set of five custom vanilla RabbitHole doors.

With "vanilla" I mean that they don't have any built-in career or other features/interactions,
except the most common ones: invest, buy and rename. Since these RabbitHole doors
come with a weird and generic name, you can rename them even if you don't own them
using a debug or a Buy/Build Mode interaction (CTRL+SHIFT+Click on the door).

If these doors have no features what's their purpose? The purpose is to use them to host
custom careers made with NRaas Careers, so those don't have to share the same location
with default careers that have nothing to do with them.

INSTRUCTIONS

How can you assign a custom career to one of the custom RabbitHole doors?

Let's take a random custom career created by Missy Hissy, mistress of custom careers ^^
I'll use her Advertising Career as example and S3PE as package manager (you can also use Postal)

(With S3PE) open the AdvertisingCareer.package

right click on the xml resource with the career data, in this case its name is "Advertising.Careers", and select Notepad from the popup menu. A new window opens.

find the RabbitHoleType tag of the career (it's not the one in the first <CareerList>...</CareerList> block, but the one in the second block)

replace its value, in this case "BusinessAndJournalism", with one of the names of the custom RabbitHole doors:

WARNING: the custom RabbitHole door, once placed, will not host the custom career right away,
but only after you save and reload the game (better quit the game instead of going back to main menu,
this is a general tip to avoid problems). The same thing happens if you place a regular RabbitHole,
this is due to how NRaas Careers work, my mod can't do much about it, but I may have an idea:

If NRaas Careers use an EventHandler (OnObjectPlacedInLotEventHandler perhaps) to intercept
when a RabbitHole is placed/moved, maybe it could re-assign the custom careers to their respective
RabbitHole using an iteration similar to that used in NRaas.Careers.OnWorldLoadFinished. Just a theory.

I'm afraid I haven't explained very well how to assign a custom career to custom RabbitHole doors,
so if you have problems just ask in the comments ^^

OTHER INFO

In Builder's Island, Sims receive the message "A car will come to take you to work in 1 hour", but
no car comes and Sims don't go automatically to work. This may happen also in other worlds,
not sure what's the reason. EDIT: To be clear, this happens also with regular rabbit holes,
there's something wrong/lacking in that world that prevents carpools and also to call services
(repair man, etc). Well, to be fair that world was not meant to be playable and it's terrific for
testing purposes, so don't think that I don't appreciate it.

Oh, I almost forgot, the custom RabbitHoles are xml tunable, you can change the investment cost, etc etc.
I also suggest you to customize to your liking their icons (the trasparent ones are those showed in map view).
